Bert - I could say the same as you, but with "play" and "sing" switch. Using only my voice, I can't carry a tune. But I'll pick up an instrument for the first time and pick out simple tunes. When I first started messing with the banjo, I'd do an alternating thumb roll on a C-G-D-G chord progression for literally hours (2-3 at a time) and enjoy the hell out of it. I wasn't practicing - I was having fun. One evening after work one of my co-workers picked up a guitar and started noodling counter rhythms over what I was doing. After about 20 minutes we finally quit, and much to my surprise our corporate CEO had been listening, and applauded! Unfortunately, that's the only time I've ever gotten to play with anyone else. All of my music is solo, with myself as the audience.
